NO$GBA <-> VBA save converter

ASk · September 29th, 2007, 13:55

Here's a small tool that I couldn't find anywhere, so I've whipped it up for my own use. It converts between NO$GBA 'raw' and VBA battery saves.

Limitations - when converting to VBA save, one must know the real save size - this is due to VBA determining save type by file size.

The tool is attached, you may need the VC8 runtime. you can find it on Microsoft's website. Usage is explained in the readme.
BACKUP YOUR FILES, I'M NOT RESPONSIBLE FOR ANY DATA LOSS THAT MAY OCCUR

edit: Seems that only certain games (specifically, ones with 32kbit save data size - an example is LoZ: Minish Cap) cause VBA to require the save game to be in little-endian format. YMMV.

I found a visual basic 6 "no$gba->vba" converter posted, which just strips the no$gba header from the data.

I've tried it, and well, it didn't really work on anything I've tried. VBA 1.8.0b3 and kode54's sse2 build do not recognize the save files properly, even when trimmed.

The reason follows -

VBA native save files are written as little-endian long longs (x86-style). no$gba saves the files in big-endian long longs (ARM7-style). In order for one to recognize the other's files, endianness conversion is required.

That, and the fact that VBA guesses save type/size by filesize and does not load the save data properly if the file is too big.

So, unless you got anything better to add, I rest my case.

VC8 runtime installed? yes/no?

no, for just a command line/dos program? well, i'll not bother anyway, but you should check in case someone really wants to use and doesn't have that too.

I downloaded it and it's Running fine for me, though I didn't try converting any save yet...
